A.2 Describes of terms
Before using this product, explain the general terms of Ethernet module. Please refer to the Ethernet technical book for
details.

Auto-MDIX(Automatic Medium Dependent Interface Crossover) The type of Ethernet cable is divided into Crossover
Cable (TX-RX, RX-TX) and Straight Cable (TX-TX, RX-RX), where the TX / RX is interchanged based on TX / RX.
Communication of each network device is possible through connection of TX (node A) -RX (node B) / RX (node A) -TX
(node B), so it is impossible to communicate with Straight Cable. However, if there is a function that can electrically
exchange TX and RX in the connected node, it is possible to communicate with each other using a straight cable, which is
called Auto-MDIX.

Auto-Negotiation Ethernet is the process by which Ethernet devices exchange information about performance, such as
operation speed and duplex mode.
1) Find out why connection was denied
2) Determine the performance of your network equipment
3) Change connection speed

ARP(Address Resolution Protocol)
Protocol to search for MAC address by means of correspondent IP address on the Ethernet LAN

Bridge
A device used to connect two networks so to be operated as one network. Bridge is used not only to connect two different
types of networks but also to divide one big network into two small networks in order to increase the performance

Client
A user of the network service, or a computer or program (mainly the one requesting services) using other computer's
resource.

CSMA/CD(Carrier Sense Multiple Access with Collision Detection)
Each client checks if there is any sign prior to transmission of data to the network (Carrier Sense) and then sends its data
when the network is empty. At this time, all the clients have the equal right to send (Multiple Access). If two or more clients
send data, collision may occur. The client who detects the collision tries to send again in a specific time.

DHCP( Dynamic Host Configuration Protocol)
Communication protocol IP standard for automatically allocating and managing setting information necessary for
executing TCP / IP communication. Provides uniform management of IP addresses in telecommunication networks in TCP
/ IP environments.
